CVE-2026-102023

An OS command injection vulnerability in the bootzd zero-touch provisioning daemon of Junos OS Evolved on PTX Series allows an unauthenticated attacker on the management LAN to execute commands as root via a crafted gRPC response.

An OS command injection vulnerability in the bootzd zero-touch provisioning daemon of Junos OS Evolved allows an unauthenticated attacker on the management LAN to execute commands as root via a crafted DHCP response.

An improper restriction of communication channel to intended endpoints vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause limited information disclosure and availability impact to the device. Due to wrong initialization, a process that should only communicate internally can be reached over the network via an open port, leading to inadvertent exposure and increased CPU cycles spent processing ingress packets.

A stack-based buffer overflow vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated remote attacker to trigger a kernel panic via a crafted TCP packet when key-chain authentication is used for BGP or LDP.

An Out-of-bounds Write vulnerability in lacpd of Juniper Networks Junos OS Evolved allows a Layer-2-adjacent attacker to cause a denial of service via a crafted frame received on an LACP-enabled aggregated-Ethernet member port.

A Reachable Assertion vulnerability in the na-grpcd process of Juniper Networks Junos OS Evolved allows a remote unauthenticated attacker to cause a denial of service via a gRPC telemetry subscription request.

An Improper Validation of Specified Quantity in Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS Evolved on PTX Series allows an unauthenticated IS-IS peer to cause a denial of service.

A use of externally-controlled format string vulnerability in the jti-dialoutd of Junos OS Evolved allows an authenticated network attacker to cause persistent telemetry dial-out denial of service via a crafted analytics sensor resource submitted through gNMI listener.

A use of externally-controlled format string vulnerability in the gRPC daemon of Junos OS Evolved allows an authenticated network attacker to cause telemetry-service disruption, information disclosure, or potential root-level code execution via a crafted message to the gNMI service.

An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS Evolved on QFX5240, QFX5241 and QFX5250 configured for BGP global-load-balancing and more than 128 ecmp next-hops allows an attacker to cause an rpd crash.
